Radiative flux and forcing parameterization error in aerosol-free clear skies. | LitMetric

AI Article Synopsis

  • Radiation parameterizations in General Circulation Models (GCMs) have improved accuracy compared to previous models.
  • There are significant errors in the estimates of the radiative forcing from quadrupling CO2, particularly with solar radiation.
  • These errors vary based on atmospheric conditions, making it difficult to determine a precise global mean error.

Article Abstract

Radiation parameterizations in GCMs are more accurate than their predecessorsErrors in estimates of 4 ×CO forcing are large, especially for solar radiationErrors depend on atmospheric state, so global mean error is unknown.

Can Thermal Nonreciprocity Help Radiative Cooling?

Research (Wash D C)

December 2024

Department of Applied Physics, Kyung Hee University, Yongin-si, Gyeonggi-do 17104, Republic of Korea.

Radiative cooling has witnessed substantial progress while its performance is constrained by the thermal reciprocal Kirchhoff's law. Violating Kirchhoff's law to pursue nonreciprocal radiative cooling seems promising; however, the energy conservation requirement and radiant flux integrated over the entire hemisphere make the nonreciprocal benefit insignificant. This commentary discusses the practical limits of nonreciprocal radiative cooling and points toward the future direction of directional radiative cooling.

Rewetting peatlands is required to limit carbon dioxide (CO) emissions, however, raising the groundwater level (GWL) will strongly increase the chance of methane (CH) emissions which has a higher radiative forcing than CO. Data sets of CH from different rewetting strategies and natural systems are scarce, and quantification and an understanding of the main drivers of CH emissions are needed to make effective peatland rewetting decisions. We present a large data set of CH fluxes (FCH) measured across 16 sites with eddy covariance on Dutch peatlands.

Cloud radiative effects (CREs) and cloud-type mean CREs depend upon how clear-sky fluxes are computed over a large area: those of the immediate environment of clouds or the regional mean clear-sky fluxes. Five convectively active regions in the Tropics, two over land (Africa and Amazon) and three over ocean (eastern and western Pacific and Atlantic), are selected to understand the influence of immediate environment of clouds on CREs. Fluxes derived from 19 years of high-resolution CERES satellite data, categorized by cloud type, are utilized.

Infrared imaging systems are crucial for guidance in supersonic vehicles due to all-weather capability, high resolution and high sensitivity. However, the imaging quality can be significantly impaired by aerodynamic thermal radiation noise. This paper incorporates cooling film that effectively eliminates the interference originating from supersonic thermal environments.
